Mechanistic dichotomy in the solvent dependent access to E vs. Z -allylic amines via decarboxylative vinylation of amino acids.

The solvent plays an important role in the photophysical properties of donor-acceptor based photocatalysts. The solvent-dependent access to E vs. Z -allylic amines was achieved via decarboxylative vinylation of amino acids with vinyl sulfones. Detailed experimental studies have been conducted to understand the role of the solvent in the reactivity and stereoselectivity of the vinylation reactions.
